Designed to house three 737 airplanes and park eight more on the apron, the 128,000-squarefoot hangar is the first of its kind to open at DEN. The heavy steel and structural concrete building features a 207-foot clear span that is nearly the length of a football field, and required 48,000 cubic yards of concrete to construct. Airport leaders attribute its reduced carbon footprint to creative problem solving by the project team. The large, specialized facility is also a template for other similarly sized hangars the airline is currently planning at strategic locations throughout the U.S.<\/p>\n
\u201cDEN is a key cog for Southwest,\u201d says Jay Fretwell, Sr., the airline\u2019s manager of Facilities Projects. Fretwell oversees a team of nine project managers who lead construction projects for the 121 U.S. airports that Southwest serves. His team develops plans with designers and builders for everything from mega-assets such as hangars to small back offices and ticket counters. When developing the recent project at DEN, Southwest worked with designers from Ghafari Associates to address the facility\u2019s inherent need to accommodate larger, more complex aircraft. \u201cWe expect this hangar to be in operation for the next 50 years,\u201d says Fretwell. \u201cIt was designed and built for airplanes that don\u2019t even exist today.\u201d<\/p>\n
For starters, the supersized facility required a supersized door. Technically five doors in one, the Megadoor stretches the length of the building with a tail pocket in the middle. The five fabric doors can fold up in sections, either individually, in groups, or all together. Above, the hangar\u2019s central overhead structural member is a box truss that stretches the full 270 feet of the hangar and weighs 180,000 pounds. The truss was so large it required special pre-installation planning by the building team from 精东影业 Construction Company. Due to FAA regulations limiting crane heights next to taxiways, 精东影业 led an extensive search to find the right combination of low boom height and high strength. In a single day, a 500-ton Hydra crane and a 300-ton conventional crane swung the truss into place and held it there until workers secured it with bolts and welds. Due to the extreme length and loading, 精东影业 used 3-D laser scans of the truss on the ground, after it was in place, and after it was roof-loaded to validate that the camber remained within tolerance. Like other facilities at DEN, Southwest\u2019s new maintenance hangar was developed with the environment in mind. As construction was getting underway, builders took note of the airport\u2019s waste concrete storage yard just across a fence from the jobsite. Working with Southwest and DEN, 精东影业 brought in a crusher and recycled the existing concrete to use as subgrade fill. This saved a tremendous amount of time and money that would have been spent acquiring, hauling and handling such material. It also significantly reduced the building\u2019s embodied carbon count.<\/p>\n<\/div><\/section>
